Those who dis Mr. Marshall and Mr. Sanow's work tend to be big bullet fixated and go to any lengths to "prove" that energy and statistics are irrelevant. Those who quote the "one shot stop" numbers tend to understand how statistics works (the only form of math in college I did decent at as it involved no Calculus) and are open minded as to the use of the stats when comparing the effectiveness of various calibers and don't read the stats too literally. It is a comparative thing, not literal.
I'm not sure why the big bullet guys care. I mean, the latest +P JHP .45 loads like the Speer gold dot 200 grainers put up impressive 90+ percentage numbers in M & S's stats. It's right up there with the .357 in its best loadings. Even the 9mm 115 +P is quite effective, though that might be the big bore guy's complaint. They just hate to see the non-American 9mm being effective at anything other than shooting rats. Or, maybe its that they have to justify .45 ball because that's all their 1911 will feed and it's down in the 60 percent range in the stats? Whatever.
If you can shoot it, yes, the .357 is VERY effective, one of the absolute best calibers for killing humans from a concealable handgun. However, the BG ain't gonna let you put your ear plugs in first, be aware of that. And, it is also somewhat barrel length dependent. Now, those stats are likely for 4" service guns, don't recall, but I think they separate out snubs now. I haven't read any of Sanow's stuff in a long time. It's interesting, but I just don't live by it.
I carry what I carry and I make sure I can use it effectively. I have .357s, but I find a subcompact 9mm auto a lot easier to put in a pocket and I ain't shootin' no Smith 12 ounce snub with a truly effective .357 rounds. IMHO, that gun is a .38 special with a long chamber.
I will say this, rather than carry a 1911, I think a lighter 4" K frame is easier to carry, though not quite as flat, and I'd far rather have 6 hot hollow point rounds out of a M13 than 7 .45 hardballs out of a 1911.
To each his own, though. If you feel your .45 or your .357 snub is the "hammer of thor" and worth the discomfort to carry, go for it. That's an individual decision. I know what works for me. That's all I really care about. I have a healthy respect for the .357 magnum's ballistics because I've seen what it can do in the field. But, even my little SP101 isn't quite as easy to carry as what I have on me 24/7, a pocket sized 9mm loaded with 115 grain JHPs at 1262 fps. I can shoot that gun very well, to, quite practiced with it even out to 25 yards on smallish targets, let alone gunfight range.
